designated generally by the numeral 27 for wrapping the flexiblecovering about the painted pipe and for securing sald covering thereon.This wrapping and securmg mechanism has not been specifically describedherein for the reason that it forms no part of the invention describedand claimed.

The numeral 28 designates a suitable hopper whose lower end is formedinto a lengthwise discharge opening as 29, which is disposed above theipe 1. This hopper is located in front of the wrapping mechamsm abovereferred to and is provided to contain a suitable pitch, aint or othersubstance with which the pipe is to be coated. The exhaust pipe 30 fromthe motor 5 terminates in the hopper 28 and supplies heat to the coatinsubstance in the hopper to assist in maintalnin the proper temperaturethereof.

Un erneath the pipe 1 and arranged opposite the hopper there is aflexible paint retainer 31 which is suspended by front and rear coilsprings 32,32 and 33, 33 whose lower ends are attached to the margins ofthe retainer 31 and whose upper ends are attached to the free ends ofthe inwardly extending arms 34, 34 and 35, 35, which are fixed on therespective shafts 36, 36. These shafts are disposed on opposite sides ofthe pipes 1 and are rotatable in suitable bearings 37, 37 carried by therespective side members 2. Each shaft 36 has an upstanding arm 38 fixedthereto. The shaft 19 has ad acent cams as 39 fixed thereon and thereare the oscillating rods 40, 41 formed at one end with the bearings 42,43 in which the cams 39 work and the other ends of these connecting rodsare pivotally connected to the upper free ends of the respective arms38. As the shaft 19 rotates the rods 40, 41 will be simultaneousloscillated and the shafts 36 rocked back an forth-and this willreciprocate the retainer 31 back and forth against the underside of thepipe 1. The coating material will be fed onto the top of the pipe 1 asrun down into the retainer 31 and as said retainer is reciprocated itwill spread said paint over the under side as well as both sides of thepipe to be coated.

Meanwhile, the frame 23 will be revolved and the wrapping will be woundonto the pi which has been freshly coated and will ad ere thereto.

The drawings and description disclose what isnow considered to be thepreferred form 'of the invention by way of illustration only, while thebroad principle of the invention will be defined by the appended claims.What I claim is 1.
